Life had been alright, for the previous twenty-two years of her existence. Being an only child her whole life was not the worst; of course, there were friends and social events and places- schooling and so on. But, there was a burning desire deep within her, all her life- the want of a sister. Life went on, and how she studied in college working towards a degree psychology and lived on her own.

Yet, when Willa turned twenty-three, the news broke out from her mother that her parents were getting a divorce. While this was a bit of a shock, the additional news of her mother already finding someone new and planning to marry them came even harsher. Turns out, the man her mother planned to marry, also had a child. A man named Jacob, who was only a year younger than herself. Both she and Jacob lived away from their parents. But, now that his father and her mother were getting together, that meant they would be step siblings.

With this news, that deep desire re-awoken within her. All it took was a few small questions to her soon to be step-father one night, on her new brother. Learning he lived not too far from herself, Willa knew what she had to do...Of course, part of her understood it wouldn't be easy-convincing someone that their life needed to change-all of it. It would take work, and the start had to be swift...Yet, she was up for the challenge.

Soon, maybe not as soon as she wanted, Willa would have her sister.

Hello!

So, the prompt is a slightly incest-based, feminization theme! My basic concept being: Willa with a chance to have a possible sister, takes her chance. A new step-brother offers her a chance, and she will invite herself over to start her plan. Ideally, I'd like a slightly more darker tone to this, to start. Willa coming over, and forcing more of the feminization. Maybe even needing to keep him in his apartment for a prolonged time as she works on crafting her new sister. Willa herself, being a little obsessed with the concept of having a sister.

One concept I find fun, is the idea of re-working his thoughts, through means of orgasm denial. Working him up day, after day-edging him hours on hours, just to deny him relief. Until he becomes what Willa wants. A slow burn, until that mind of his cracks and she can craft the prefect step-sister. She might have to move into his apartment to keep the treatment up, reworking his mind. And at first. I'd like Jacob not to be open to just becoming more feminine and lady like. After some time, and his mind melting from lack of orgasm, he will see the light.

Ideally, I would like a partner to write as Willa. Her appearance is open for debate! I would like to write as Jacob, Willa's step-brother to become step-sister(Sissy). Also, be open to write in 3rd person, please.

Possible Kinks: Orgasm control/Denial. Prolonged Denial. Edging. Chastity cages (because she needs to keep his cock around to edge him.) Mental/memory/functional issues through prolonged denial. Brainwashing to a degree. Feminization. Panties. Ruined Orgasms. Cbt/Ballbsuting. Humbers. Face-sitting. Bondage. Blindfolds, and more!

Limits: Cucking. Blood/Gore/guro. Scat/bathroom kinks. Puke. Bad smells. Feet. Impregnation.
